Mining-
The process of extracting economic minerals,Coal or Ore,etc from the Earth Crust is know as Mining.
And the place where this type of process including searching Operations is done this place is known as Mine.
mining Methods are divided into two groups-
1.Surface Mining
2.Under Ground Mining.
1.Surface Mining-Are those mining operations which is done in or above the earth surface is called Surface mining.

Types of Mining Methods-
mining Methods are divided into two groups-1.Surface Mining
2.Under Ground Mining.
1.Surface Mining-Are those mining operations which is done in or above the earth surface is called Surface mining.
Types of Surface Mining
Now here are various different types of Surface mining-
1.Open Cast Mining
2.Placer Mining
3.Auger Mining
4.Dredging Mining
5.Hydraulic Mining
6.Strip Mining
Open Cast Mining-
Open Cast or Pit mining is a method of mining in which first removal of overburden is done and there after layers of ore or mineral to be excavated.

Machineries used in O/c Mining -
in this mining large type of machineries are used to extract the coal or Ore, which are Commonly Known as HEMM { Heavy Earth Moving Machines}.
in this mining large type of machineries are used to extract the coal or Ore, which are Commonly Known as HEMM { Heavy Earth Moving Machines}.
These machineries are-
Dragline,Shavel,Bucket Wheel Excavator,Front End Loader,Dozer,Dumper,Drill Machines,etc.
2.Under Ground Mining- Are those mining operations which are done below the earth surface is called Under Ground mining. this mining adopted when the Ore or Coal are found in higher depth.
